My previous post was about Curl library for CodeIgniter. And now it’s time to tell you a main secret - how we will check Google PageRank in Mass PageRank Checker tool.

As I started development with CodeIgniter, I wrote a little CI-helper for SEO functions and added Google PageRank cheking function. Later I will add other useful functions to this helper.

You can download SEO helper here.

You wanna ask me how I did it? It’s quite simple! I learned the code of seo4firefox addon (it’s javascript) and wrote the same in PHP :-)

To install it you need copy seo_helper.php file to the system/application/helpers folder of your CodeIgniter instance.

And now let’s see the example of using.

$this->load->helper('seo');
$pr = pagerank('http://alexpolski.com/');

It’s more than simply! Enjoy!
